CAR-HAU L.

SPECIFIGATIQN forming part of Letters Patent No. 692,496, dated February 4, 190.2'.l

Application fled October 1,1901| Serial No. 77,555. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, ALFRED M. AcKLlN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and usefullmprovement in Car- Hauls; and I do herebydeclare the following to be a full, clear, and exact description thereof.

My invention relates to car-hauls, and has special reference to the uphaul-chain for engaging and moving the car.

The object of my invention is to provide a cheap and simple form of a car-haul which will have a much greater capacity than ordinary chain car-hauls which have equal weight and strength of chain, shafting, gearing, zc.

My invention consists, generally stated, in the novel arrangement,construction,and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved car-haul, I will describe the same more fully, referring to the accompanying drawings, in which- Figure 1 is a side View of my improved carhaul. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged detail view of the connecting portion of the car-haul chains.

Like symbols of reference herein indicate like parts in each of the figures of the drawings.

As illustrated in the drawings, the tracks are shown at 1 and are provided with the portions 2 2' thereon, with inclined portion 3 between them, and upon these tracksl the cars are adapted to travel. Between the inclined portion 3 of the tracks 1 is preferably located the main uphaul-chain 5, which is provided with a series of hooks or projections 6 thereon for engaging` with a bar 4' on the cars -1 and passes around sprocket-Wheels 7 7', which are mounted on shafts 8 S', and said chain being guided by the guide-rollers 9', which are located adjacent to the upper sprocket-wheel 7 and are mounted on shafts 10. Extending preferably between the inclined portion 3 of the tracks 1 and below the main uphaul-chain 5 is another uphaul or secondary chain 11, which is provided with the hooks l1' thereon and passes around sprocket-wheels 12 12',

The chain 11 is opmounted on shafts 13 13'.

erated by means of a sprocket-chain 14, which passes around a sprocket-wheel 15, mounted on the shaft 13, and a smaller sprocket-wheel 16, mounted on the shaft 8', located below the sprocket-Wheel 12 and shaft 13. Extending preferably between the portions 2 of the tracks 1 and for a short distance up the inclined portion 3 thereof is the auxiliary chain 17, which passes around a sprocket-wheel 18, located above the sprocket wheel 12' and shaft 13 and mounted on a shaft 18', and around another sprocket-wheel (not shown) located at the front of the chain 17. The chain 17 is provided with the hooks 17 thereon and is operated by means of a sprocketchain 10, passing around a sprocket-wheel 20, mounted on the shaft 1S', and around a smaller sprocket-wheel 21, mounted on the shaft 13', located below the sprocket-wheel 1S and shaft 1S'.

The use and operation of my improved carhaul is as follows: Power being preferably applied to the upper shaft 8 in any suitable lnanner will act to turn said shaft S, and with it the main uphaul-chain 5, which passes around the sprocket-wheels 7 7'l on the shafts S S', respectively, and as the chain 5 is thus moved it will act to move the other uphaulchain 11, which passes around the sprocket- Wheels 12 12' on the shafts 13 13', respectively, at a slower rate of speed than the chain 5 on account of having the sprocket-wheel 16 on the shaft 8' smaller than the sprocket-wheel 15 on the shaft 13 and connected by the sprocket-chain 14. The movement of the secondary uphaul-chain 11 also acts to move the auxiliary chain 17, passing around the sprocket-wheel 18 on the shaft 18' and around the sprocket-wheel, (not shown, but mounted at. the front of the chain 17,) at a still slower rate of speed than the chain 11 on account of having the sprocket-wheel 21 on the shaft 1,3 smaller than the sprocket-wheel 2O on the shaft lSand connected by the sprocket-chain 19. rPhe cars 4 are brought at aslow rate of speed to the foot of the lower uphaul-chain 11 on the portions 2 of the tracks 1 through the medium of the chain 17 and by means of the hooks 17 on said chain 17 engaging with the bars 4 on said cars 4, and as the chains 11 and 17 overlap each other at this point the hooks 11' on the lower uphaul-chain 11 will catch or engage with the bars 4' on the cars 4 at about t-he time hooks 17 on the chain 17 are disengaged from said bars 4' on the cars 4 and canse said cars to travel up the inclined portion 3 of the tracks 1 by means of the lower uphaul-chain l1 and at a somewhat faster rate of speed than that at which they were brought to the uphaul-chain 11 by the chain 17. The uphaul-chain 11 and the main uphaul-chain 5 overlap each other at the point Where they meet, and when the cars 4 are brought up to the foot of the main uphaul-chain 5 by the hooks 11 on the chain 11 engaging with the bars 4' on the cars 4 the hooks 6 on said chain 5 will catch or engage with the bars 4 on the cars 4 at about the time the hooks 11 on the chain 11 are disengaged from said bars 4/ on the cars 4 and cause said cars to travel up the portion 3 of the tracks 1 by means of the main uphaul-chain 5 and at a still somewhat faster rate of speed than that at which they were brought to the chain 5 by the chain 11. After the cars 4 have traveled up the inclined portion 3 of the tracks l by means of the main uphaul-chain 5 and have reached the point adjacent to the sprocket-Wheel 7 the hooks 6 on said chain 5 will become disengaged from the bars 4 on said cars 4, and said cars can pass along the portion 2 of the tracks 1 to any place desired.

It will be evident that under some conditions the hooks on the several chains can engage with the axles of the cars or any other point or object thereon, and so do away with the engaging bar, and that any number of chains operated at different speeds can be elnployed. It will also be evident that thechains can be placed outside ot' the tracks, if desired, and various other modifications in the construction, design, and operation of the carhaul may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

It will thus be seen that my improved carhaul is cheap and simple in its construction and operation, and by its use the heavy strain and jolting to a single uphaul-chain is overcome, while the device will permit as many cars to be hauled up the car-haul as in ordinary cases by the employment of muchlighter chains and ot' the dilerent speed of such chains. By the use of a high speed on the main chain the cars may be spaced a long distance apart and still get the required number of cars delivered at the head of the incline in a given space of time; but since it is impractical to start the cars suddenly from a secondary traveling chain having hooks thereon for-engaging with the car, and a main traveling chain having hooks thereon for engaging with the car and adapted to travel at a greater speed than the iirst-named chain.
